I really like what you did with the theme for this one. I was immediately murdered the first round I tried, and the second round I got some terrible weapon with a super short range. After that I figured out what the buffs/debuffs did and enjoyed it. The only issue I ran into was that at one point there were several debuffs on the screen and nothing else seemed to spawn, it might be a nice idea to have the buffs/debuffs disappear after a short time so that more can cycle through.
